PIPE STRUCTURE.

Application filed. May lo,

To all whom it may concern.

Be it known that I, FLoYn Dow, a citizen of the United States, residingat lVyanet in the county of Bureau and itate of Illinois have invented anew and useful Improv ment in Pipe Structure, of which the "following isa specification.

My invention relates more particularly to pipe structures formed of pipemembers connected together at adjacent ends, and the pipe members beingto med in sections each preferably he it cylindrical, the joints betweeneach extending lengthwise of the pipe members,' such a character ofconstruction being desirable under some conditions where the pipemembers are cast from metal.

My primary object is to provide a pipe structure of the character abovereferred to wherein by a novel, simple and economical construction ofmeans, the pipe sections may be held tigh 1y together and adjacent pipemembers be rendered relatively rotatable and other objects as willappear from the following description Referring to the accompanying drawings:-

Figure l is a section taken at the line 11 on 2 and viewed in thedirection of the arrows. this View showing the coupling in section andthe lnilf-cylindrical pipe section in elevation. 2 is a section taken atthe line 2 on Fig. l and viewed in the direction of the arrow. showingthe upper end of the construction illustrated in Fig. i. Fig. 3 is asection taken at theline 3 on Fig. 1 and vieweu in the direction oi thearrow. F 1- is a plan view of the structure shown in Fig. and Fig. 5 aplan View of. the structure of Fig. 2 with the coupling removed.

of the similar pipe members employed is represented at 6, these pipemembers which are either straight or of elbow or angle form and or anylength desired, to suit the particular condition of use prebeing eachtermed of sections. each rably in the form of a lnllt-cyliiuler, as epreented of the sections 7 and S forming moi/rated pipe-member 6. ihesections are so formed as to provide a tight extending lengthwisethereof: when these pipes are assembled to form the pipe member, whichin the construction shown is cylindrical, it being preferred that thesejoints be formed by casting, where pipe members are produced by thecasting opera Specification of Letters Patent.

tion a longitudinally extending groove 9, along one edge of each pipesection and a longitudinzlly extending tongue along the other,diametrically opposed, edge, the tongues 10 being adapted to entertheopposed grooves 9 in the opposed pipe sec ticns as reoresented inFig. 3. to form tight joints between these sections, the rooves 9 andtongues 10 being preferably iiormed in ribs 11 and 12 provided on theexterior of the pipe sections. these ribs by preference reaching shortof the ends of the pipe member as represented of the one in Fig. 1, thepipe member thereby presenting at opposite ends the cylindrical portions13.

T he pipe sections 7 and S are held together in the assembled positionreferred to, by ring-like structures forming couplings hich in additionto holding the pipe sections together, form means for connectingtogether the adjacent ends of pipe members in a ma ner to render themrelatively rotatable. In the drawings I have illustrated a desirableform of such a coupler this coupler being represented at lat and beingprovided at its opposite ends on its inner surface withcircumrerentially disposed grooves 15, with notches 16 opening intothese grooves through the opposite ends of the coupling. The coupling1-1- is prelierably cast and by preference its ends are of bead form asrepresented at 1? and in which the grooves 15 are located. The notches16 at each end of the coupling 11'- may be diametrically opposed, orotherwise disposed in spaced relation. about the circ .lar ends of thecoupling. the e notches cooperating with studs 18 provid on thecylindrical porti us l of the pipe member (3, the studs I being spacedapart about the circum erence of the pipe member 6 a distancecorresponding to the spacing of the notches 16. whereby the studs 18 mayenter the notches 16 at the end of the coupling 1 nd pass intoregistration with the groove 15, after moving the coupler and pipemember into telescoping condition. the studs 18 entering the groove 15and interlocking wi h the nnnotched portion thereof upon relativelyrotating the coupler iiand pipe member (3.

in the assembling of the parts of the structure the sections 7 and S arejoined together by entering the tongues 10 in the grooves 9 representedin Fig. 3 and conplings such as those shown at 14 are applied to theopposite ends of the pipe member thus produced, to firmly secure thesepipe sections together and form a rotatable connection between thecoupler l4: and pipe member, it being understood that the structureshown in Fig. l is merely illustrative of the assembly of the pipesections relative to each other and with a coupling and that in practiceanother one of the pipe members 6 of any form desired would connect withthe upper end of the coupling 14: and this arrangement would becontinued for the full length of the pipe structure desired to beproduced.

It will be understood from the foregoing that the various elementscomprising the pipe structure may be assembled quickly and when desiredquickly disassembled by rela-- tively rotating the pipe members andcouplings. Furthermore, the feature of the pipe members and couplingsbeing relatively rotatable, adapts the pipe members, whether of angle orelbow form or provided with deflected ends, to extend in the desiredpositions relative to each other, which is especial value in connectionwith the structure when used for stove-pipe purposes; and while I havereferred to the use of the invention in connection with the productionof stove pipes, it will be understood that it may be utilized in pipestructures for other purposes as well.

lV hat I claim as new and desire to secure by Letters Patent is 1. Apipe structure formed of a plurality of pipe members disposed in end toend relation, and each formed of sections extending lengthwise thereof,and means engaging the ends of said pipe members operating to hold saidpipe sections in assembled condition and permit of the relative rotationof adjacent pipe members. i

'2. A pipe structure formed of a plurality of pipe members disposed inend to end relation, and each formed of sections extending lengthwisethereof, and means engaging the ends of said pipe members operating tohold said pipe sections in assembled position and interlock with saidpipe members to prevent longitudinal separation thereof except at apredetermined position of said members relative to said means andpermitting relative rotation of said pipe members.

3. A pipe structure formed of a plurality of pipe members disposed inend to end relation and each formed of sections extending lengthwisethereof and ring-shaped coupling members surrounding the ends of saidpipe members and operating to hold said sections in assembled conditionand connect adjacent pipe members together and permit relative rotationof said coupling members and pipe members.

4. A pipe structure formed of a plurality of pipe members disposed inend to end relation and each formed of sections extending lengthwisethereof and'ha'ving studs on their circumferences at the ends thereof,and ring-shaped coupling members surrounding the ends of said pipemembers and holding said sections in assembled condition and connectingadjacent pipe members together, said coupling members containingcircumferentially disposed grooves on their inner surfaces at theirends, with notches opening into said grooves and through the ends ofsaid coupling members for registration with 7' said studs and throughwhich notches the studs of adjacent pipe members enter said grooves forinterlocking with the walls of the latter, in the assembling operation.

5. A pipe structure formed of a plurality of pipe members disposed inend to end relation and each formed of'sections extend ing lengthwisethereof, said sections at the lengthwise extending joints therebetweenbeing relatively overlapped, and means engaging the ends of said pipemembers operating to hold said pipe sections in assembled condition andpermit of the relative rota tion of adjacent pipe members.

6. A pipe structure formed of a plurality of pipe members disposed inend to end relation and each formed of sections extendinglengthwise'thereof, each of said sections presenting a groove along oneedge and a tongue along 1ts opposite edge extending lengthwise of thesection, with the tongues of opposing sectionsextending into the opposedgrooves thereof, and means engaging the ends of said pipe membersoperating to hold said pipe sections in assembled condition and permitof the relative rotation of adjacent pipe members.
